'Space jellyfish' lights up predawn skies over the DC area

A predawn SpaceX Falcon 9 launch created a glowing, jellyfish-like plume that was visible across the DC region under clear skies.

Early morning skywatchers were treated to quite a spectacle as a SpaceX Falcon 9 rocket launched from Cape Canaveral and streaked northeast across the predawn sky.

The launch occurred at 5:10 a.m. Tuesday and was visible throughout the Mid-Atlantic thanks to clear skies. As the rocket climbed higher, its sunlit exhaust plume created the appearance of a glowing "space jellyfish" against the still-dark sky.

"This occurs when a rocket and its expanding exhaust plumes are illuminated by the sun while observers remain in local darkness," explained the X account Space Jellyfish Alerts, which tracks launches capable of producing the phenomenon.

Because the rocket reached high altitudes while the sun was still below the horizon in the Mid-Atlantic, it was visible across a wide swath of the eastern United States.

Here are some photos and videos of the spectacle shared by Capital Weather readers:
